As clearly shownin the sectional views 2 and 4, respectively; the upper eorrugw tione are stamped outwardly, whereas the lower are stamped inwardly, and likewise one of the corrugafions 3, on one side of the. panel is stamped inwardly and the other on the opposite side is stamped outwardly.

Thus when the panels are secured to one another, the rospeotim oorrugatione 3 and 3, 11ml 4 and :l, curve away from one on 50 other, afiording an inner: and. outer Ell) in toeoul the center oil' hi poo now 1 Fl 1 l ,oo of minidopth, liol'llooteh by the relmenoe 1111-- and that of nmxinmm depth lay enee numeml ll. lln be nilolflifhxurtion illustrated in Figs. 7 to incl gi e, I have shown :L panel 12 Fir-night. oorrugmiions, (ooh corrugn mien it If vorylng in lepf and. success 4 lowing 1, greater varh'llitm in depth from new tho edge [10 the center of the plate or panel.

In the particular form of corrugated plate shown in my invention, I have constructed the some so that the corrugations are disposed above and below the flat surface of the plate and the panel so constructed. is sobeniuotlelv of uniform strength, asmming o, symmetrically disposed load. In all prov: 5; types of C(H'llilgatfid structures, the metal. has been preesed, out only on one side and hence is materially weakened. thoreby, pm'fiieularly with regard to with ever, in my invention, due to the fact that the :meiael is eorru ated in bot-h directions reletivo the 110mm plane of the plate, the initial. tensile stress imposed thereon is reatly reduced and. furthennore such a isposltion of the corrugations enables the plates lo Withstand oompres. ion from each side equally well.

n u =e the };m1"tioulm' variation in the flffii'illlC-llilfi corrugatmos may be 41 lll'fillfld in oooh case. For inthe greot est depth ml be made at 3 nt of center of pxoseore as where the poo are mo for oar ends of cars can 111g grain or a lo homogeneous cozvtents. hot is; to say, the disposition of the worm utlons need not; be symmetrical about a central axis, but; the corrugations may be formed to suit the particular conditions under which the panel is to he need.

I aroeware that. various details of 0011- etruotion may be varied through a wide range Without departing from the principles of this invention. I therefore do not pur pose limiting the patent granted. otherwise than necessitated by the prior art.

I claim as my invention:

1. A plate normally fiat at its edges which constitute supporting points and provided with a plurality of corrugations in its surface within said edges, sold corrugations arranged. to increase in depth symmetrically on lmth faces between. mid elges and, at given [)llilfllif; in the 7 1:: lie.

4. A plate normally fiat at its edges which edges, said corrugations arranged to increase in depth symmetrically on both faces between said edges and at given points in the plate.

3. A plate normally flat at its edges which constitute supporting points and provided with a plurality of corrugations extending outwardlyon each side of the normal plane of the plate, the depth of said corrugations increasing on both s des of the plate from near the points of the support of the plate constitute supporting points and provided with a plurality of concentric corrugations; thedepth of said corrugations increasing on both sides of the plate from near the points of support of the plate toward the, middle thereof.

A plate normally flat at its edges which constitute supporting points and provided with a plurality of concentric corrugations extending outwardly on each side of the normal plane of the plate, corrugations increasing on both sides of the plate from near the points of support of the plate to the middle thereof.
